A new way of making electricity

A. But that isn't the end of the story.

B. This kind of information is very useful for certain people.

C. Why not use the energy created by pedestrians instead?

D. However, one big problem could be cost.

E. And it's actually based on a simple idea.

F. This is especially true when it's been used in very busy areas.

G. But it soon became clear that this might not work.

H. This new system should work even better.

 

Ever since the 19th century, when people were developing different ways of creating electricity, companies have looked for improved ways of producing power, using cleaner and more efficient methods.

Now a UK company called Pavegen has been working on technology that could be widely used in the future to produce electricity. 1   The company has developed a special type of floor, made of square tiles. Underneath each square, there's a system that can produce a certain amount of electricity very cheaply — from the energy created every time someone steps on it!

The creator of the floor, Laurence Kemball-Cook, came up with the idea when he was a student, and did some work experience with an energy company. The company asked him to investigate ways of providing street lighting in city centres, using energy from the sun to produce electricity.

2   One reason was that many city centres don't get enough sunlight, because of all the tall buildings. Then he thought of a better plan.

3   The right technology could be used to convert this energy into electricity — right under people's feet!

The design of the floor is actually extremely effective. 4   And the reason is that a lot of energy is produced simply because of the large numbers of people walking across the floor. In fact, the special squares are already in place in several locations with high numbers of pedestrians. These include big department stores and also an airport.

The Flooring can have other uses too, such as recording how many people visit a shopping centre at particular times. 5   For example, shop owners in the centre would be interested in knowing at which times of days they have the highest customer numbers. So the next time you visit a big shopping centre, have a careful look at the floor that you're walking across!

Reading the following passage and mark the letter A, B, C or D on you answer sheet to indicate the correct word for each of the blanks.

The growth of cities, the construction of hundreds of new factories, and the spread of railroads in the United States before 1850 had increased the need for better illumination. But the lighting in American homes had improved very little over that of ancient times. Through the colonial period, homes were lit with tallow candles or with a lamp of the kind used in ancient Rome – a dish of fish oil or other animal or vegetable oil in which a twisted rag served as a wick. Some people used lard, but they had to heat charcoal underneath to keep it soft and burnable. The sperm whale provided superior burning oil, but this was expensive. In 1830 a new substance called “camphene” was patented, and it proved to be an excellent illuminant. But while camphene gave a bright light it too remained expensive, had an unpleasant odor, and also was dangerously explosive.

Between 1830 and 1850, it seemed that the only hope for cheaper illumination in the United States was the wider use of gas. In the 1840s, American gas manufacturers adopted improved British techniques for producing illuminating gas from coal. But the expense of piping gas to the consumer remained so high that until the mid–nineteenth century gas lighting was feasible only in urban areas, and only for public buildings for the wealthy. In 1854, a Canadian doctor, Abraham Gesner, patented a process for distilling a pitch like mineral found in New Brunswick and Nova Scotia that produced illuminating gas and an oil that he called “kerosene” (from “keros”, the Greek word for wax, and “ene” because it resembled camphene). Kerosene, though cheaper than camphene, had an unpleasant odor, and Gesner never made his fortune from it. But Gesner had aroused a new hope for making illuminating oil from a product coming out of North American mines.

The word “this” in paragraph 1 refers to _______.

A. oil 

B. charcoal

C. lard

D. wick

Giải thích:

Từ “this” ở đoạn 1 đề cập đến _______.

A. dầu B. than đá C. mỡ lợn D. gạch

Thông tin: The sperm whale provided superior burning oil, but this was expensive.

Tạm dịch: Cá nhà táng cung cấp dầu đốt cao cấp, nhưng đắt đỏ.

Chọn A

Dịch bài đọc:

Sự phát triển của các thành phố, việc xây dựng hàng trăm nhà máy mới và sự lan tỏa của đường sắt ở Hoa Kỳ trước năm 1850 đã làm tăng nhu cầu chiếu sáng tốt hơn. Nhưng ánh sáng trong nhà của người Mỹ đã được cải thiện rất ít so với thời cổ đại. Trải qua thời kỳ thuộc địa, những ngôi nhà được thắp sáng bằng những ngọn nến hay đèn dầu được sử dụng ở La Mã cổ đại – một đĩa dầu cá hoặc dầu động vật hoặc thực vật khác, trong đó một miếng giẻ xoắn được dùng làm bấc. Một số người sử dụng mỡ heo, nhưng họ phải đốt than bên dưới để giữ cho nó mềm và dễ cháy. Cá nhà táng cung cấp dầu đốt cao cấp, nhưng nó đắt đỏ. Vào năm 1830, một chất mới có tên là “camphene” đã được cấp bằng sáng chế, và nó đã chứng tỏ là một chất chiếu sáng tuyệt vời. Nhưng trong khi camphene" phát ra ánh sáng rực rỡ thì nó vẫn đắt, có mùi khó chịu và cũng có thể gây nổ nguy hiểm.

Giữa năm 1830 và 1850, dường như hy vọng duy nhất cho việc chiếu sáng rẻ hơn ở Hoa Kỳ là việc sử dụng khí đốt rộng rãi hơn. Vào những năm 1840, các nhà sản xuất khí đốt của Mỹ đã áp dụng các kỹ thuật của Anh để sản xuất khí đốt từ than đá. Tuy nhiên, chi phí cho khí đốt cho người tiêu dùng vẫn ở mức cao đến mức cho đến giữa thế kỷ 19, khí đốt chỉ khả thi ở các khu vực đô thị, và chỉ dành cho các công trình công cộng cho người giàu. Năm 1854, một bác sĩ người Canada, Abraham Gesner, được cấp bằng sáng chế cho quá trình chưng cất một loại chất giống như khoáng chất tìm được ở New Brunswick và Nova Scotia, sản xuất khí đốt và dầu mà ông gọi là “dầu hỏa” (từ “keros”), từ sáp trong tiếng Hi Lạp và "ene" vì nó giống như camphene). Dầu hỏa, mặc dù rẻ hơn so với camphene, có mùi khó chịu, và Gesner không bao giờ kiếm được nhiều tiền từ nó. Nhưng Gesner đã làm dấy lên một hy vọng mới cho việc sản xuất dầu chiếu sáng từ một sản phẩm đến từ các mỏ ở Bắc Mỹ.
